The invention discloses an oval-shaped electronic cigarette and manufacturing process thereof. Inner housing of vaporization assembly is arranged inside outer housing of vaporization assembly and sleeved on vaporization assembly which comprises e-cigarette liquid cup and vaporizer having an outer wall in close fit with inner wall of the inner housing of vaporization assembly. A space is formed between outer wall of the e-cigarette liquid cup and inner wall of the inner housing of vaporization assembly to serve as a vapor flow channel. The inner housing of vaporization assembly is arranged at one end with vapor flow outlet, the outer edge of which is hermetically connected with and pressed against bell-mouth structure formed on the mouthpiece.

A cartomizer assembly of an electronic cigarette which is formed from automated assembly compatible parts comprises a container assembly including a container and a heater coil surrounding a wick in an airflow space of the container. The entire coil of the heater coil is inside the container and the heater coil is configured to heat liquid on the wick to generate an aerosol mist during a vaporization process. A liquid storage space is in liquid communication with the wick and is operable to supply liquid to the wick. The heater, the wick, and the container are shaped such that the heater and wick can be dropped into the container during automated assembly thereof and be directed to and located at a desired location in the container.

Features relating to a laser etching and/or tag writing machine are provided. The machine may include a tray assembly including a tray and a nest. The tray may hold an array of vaporizer cartridges. The tray may allow for a laser-etching operation to be performed by the machine on at least one or two sides of the vaporizer cartridges held by the tray. The tray may allow for the array of vaporizer cartridges to be rotated at the same time between laser etching operations. The tray may additionally and/or alternatively allow for the machine, such as via an antenna, to write data to an NFC tag of a corresponding vaporizer cartridge before, during, and/or after each laser etching operation.

A laser soldering device for laser soldering an electric circuit of a heating portion of an electronic cigarette, the soldering device including a head having an emitting area where a laser beam is emitted and a feeding device to feed a heating portion of an electronic cigarette along a feed path, where the heating portion faces the head at the emitting area. A movement device is operatively connected to the head to move the head between first and second points of the electric circuit such that the laser beam is perpendicular to the respective surface to be soldered at the first and second points to form first and second connections, respectively. The head generates two distinct pulses of the laser beam at the first and second points.

A method for automated manufacturing of e-vapor devices may include establishing a procession of partially assembled, oriented cartridge units of the e-vapor devices in an assembly path. The method may additionally include preparing the cartridge units for filling while the cartridge units are moving on a first drum-to-drum transport path of the assembly path. The method may also include adding liquid to the cartridge units while the cartridge units are moving in a filling workstation of the assembly path. The method may also include preparing the cartridge units for sealing while the cartridge units are moving on a second drum-to-drum transport path of the assembly path. The method further includes sealing the cartridge units while the cartridge units are moving in a sealing workstation of the assembly path.

A bubble removal preparation device and method for a gel-state electronic liquid (e-liquid) are provided. The preparation device includes a negative-pressure chamber and a cooling element, where the negative-pressure chamber is provided therein with a porous e-liquid containing chamber. A temperature controller is configured to control the temperature of the cooling element, and a gap between the porous e-liquid containing chamber and the cooling element forms an e-liquid containing cavity.

An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.
